DETAILED DESCRIPTION

FIG. 1 is a block diagram illustrating an example transaction system 100for wirelessly executing transactions using an intelligent cardindependent of a host device. For example, the system 100 may include amicoSecure Digital (microSD) card that executes transactions withfinancial institutions independent of a host device. Aside from microSD,the system 100 may include other mass storage interfaces that connect anintelligent card to the host device such as, for example, MultiMediaCard(MMC), SD, Universal Serial Bus (USB), APPLE iDock, Firewire, and/orothers. An intelligent card is a device configured to insert into orotherwise attach to a host device and access or otherwise executeservices (e.g., transactions) independent of the host device. In someimplementations, the intelligent card may be shaped as a microSD cardincluding, for example, notches, raised portions and/or other features.The system 100 may include an intelligent card that includes a dualinterface. The dual interface may connect the intelligent card to boththe host device through a physical interface (e.g., SD, MMC, USB) andexternal devices through a wireless connection (e.g., NFC, ISO 14443).In some implementations, the intelligent card may include an embeddedsecure chip, Central Processing Unit (CPU) with operating system, localmemory and value added applications accessible by the user through thehost device. A host device may include a cellphone, a smartphone, aPersonal Digital Assistant (PDA), a MPEG-1 Audio Layer 3 (MP3) device, adigital camera, a camcorder, a client, a computer, and/or other devicethat includes a mass memory and/or peripheral interface. In someimplementations, the intelligent card can operate as a master with thehost device being a slave such that the intelligent card controlsoperational aspects of the host device such as a user interface. Theintelligent card in the system 100 may execute one or more of thefollowing: selectively activate an antenna for wireless transactions inresponse to at least an event; verify the host device with a financialinstitution through, for example, a Point Of Sale (POS) using a hostsignature; execute a transaction with a financial institution through,for example, a POS terminal independent of the host device; and/or otherprocesses. By providing an intelligent card, the system 100 maywirelessly execute transactions with financial institutions withouteither requiring additional hardware, software, and/or firmware on thehost device and/or without requiring changes to existing hardware,software, and/or firmware for reader terminals to enable a user towirelessly execute a transaction.

At a high level, the system 100 includes an offline store 102 andclients 104 a and 104 b coupled to financial institutions 106 through anetwork 108. While not illustrated, the system 100 may included severalintermediary parties between the financial institution 106 and thenetwork such as, for example, a transaction acquirer and/or a paymentnetwork host. The offline store 102 includes a mobile device 110 ahaving a transaction card 112 a and a Point of Sale (POS) device 114that executes transactions with customers. The POS device 114 includes aGraphical User Interface (GUI) 109 for presenting information to and/orreceiving information from users. In some implementations, the POS 114may transmit a request to execute a transaction to the transaction card112. The transaction card 112 may transmit authentication information tothe POS 114. The client 104 includes the GUI 115 for presentinginformation associated with the system 100. The client 104 a includes acard reader 116 that interfaces the transaction card 112 c with theclient 104 a. The financial institution 106 may authorize thetransaction based, at least in part, on information transmitted by thetransaction card 112. The mobile device 110 includes a GUI 111 forpresenting information associated with financial transactions.

The offline store 102 is generally at least a portion of an enterprisehaving a physical presence (e.g., building) for operations. For example,the offline store 102 may sell goods and/or services at a physicallocation (e.g., a brick-and-mortar store) directly to customers. In thisexample, the offline store 102 buys or otherwise receives goods (e.g.,produce) from distributors (not illustrated) and then may sell thesegoods to customers, such as users of the mobile device 110. In general,the offline store 102 may offer face-to-face experiences with customersin providing goods and/or services. For example, the offline store 102may be a click-and-mortar store such that a user selects a good orservice using the Internet and purchases and receives the good orservice at the offline store 102. The offline store 102 may provide oneor more of the following services associated with goods: inventory,warehousing, distribution, and/or transportation. As a result, theoffline store 102 may not immediately distribute goods received fromdistributors. The offline store 102 may include a single retailfacility, one or more retail facilities at a single geographic location,and/or a plurality of retail facilities geographically distributed. Insome cases, two or more entities may represent portions of the samelegal entity or affiliates. For example, the offline store 102 anddistributors may be departments within one enterprise. In summary, theoffline store 102 may wirelessly execute financial transactions with themobile device 110.

Each mobile device 110 comprises an electronic device operable tointerface with the transaction card 112 a. For example, the mobiledevice 110 may receive and transmit wireless and/or contactlesscommunication with the system 100. As used in this disclosure, themobile devices 110 are intended to encompass cellular phones, dataphones, pagers, portable computers, SIP phones, smart phones, personaldata assistants (PDAs), digital cameras, MP3 players, camcorders, one ormore processors within these or other devices, or any other suitableprocessing devices capable of communicating information with thetransaction card 112. In some implementations, the mobile devices 110may be based on a cellular radio technology. For example, the mobiledevice 110 may be a PDA operable to wirelessly connect with an externalor unsecured network. In another example, the mobile device 110 maycomprise a smartphone that includes an input device, such as a keypad,touch screen, mouse, or other device that can accept information, and anoutput device that conveys information associated with a transactionwith the offline store 102, including digital data, visual information,or GUI 111.

The GUI 111 comprises a graphical user interface operable to allow theuser of the mobile device 110 to interface with at least a portion ofthe system 100 for any suitable purpose, such as authorizingtransactions and/or displaying transaction history. Generally, the GUI111 provides the particular user with an efficient and user-friendlypresentation of data provided by or communicated within the system 100and/or also an efficient and user-friendly means for the user toself-manage settings and access services offered by the financialinstitution 106. The GUI 111 may comprise a plurality of customizableframes or views having interactive fields, pull-down lists, and/orbuttons operated by the user. The term graphical user interface may beused in the singular or in the plural to describe one or more graphicaluser interfaces and each of the displays of a particular graphical userinterface. The GUI 111 can include any graphical user interface, such asa generic web browser or touch screen, that processes information in thesystem 100 and presents the results to the user.

The transaction card 112 can include any software, hardware, and/orfirmware configured to wirelessly execute transactions with the POSdevice 114. For example, the transaction card 112 may execute acontactless transaction with the POS device 114 independent of themobile device 110 a. In other words, the transaction card 112 maywirelessly execute transactions without aspects of the transaction beingexecuted by the mobile device 110. The transaction card 112 may executetransactions with the POS device 114 using short range signals such asNFC (e.g., ISO 18092/ECMA 340), ISO 14443 type A/B, ISO 15693, Felica,MiFARE, Bluetooth, Ultra-wideband (UWB), Radio Frequency Identifier(RFID), contactless signals, proximity signals, and/or other signalscompatible with retail payment terminals (e.g., POS 114). In someimplementations, the transaction card 112 may include one or morechipsets that execute an operating system and security processes toindependently execute the transaction. In doing so, the mobile device110 does not require additional hardware, software, and/or firmware towirelessly execution a transaction with the POS 114 such as an NFCtransaction. In some implementations, the transaction card 112 mayexecute one or more of the following: wirelessly receive a request fromthe POS device 114 to execute a transaction and/or and provide aresponse; translate between wireless protocols and protocols compatiblewith the transaction card 112; translate between transaction-cardprotocols and protocols compatible with mobile device 110; present andreceive information (e.g., PIN request, PIN) from the user through theGUI 111; decrypt and encrypt information wirelessly transmitted betweenthe transaction card 112 and the POS 114; execute applications locallystored in the transaction card 112; selectively switch the antenna ofthe transaction card 112 on and off based, at least in part, on one ormore events; execute authentication processes based, at least in part,on information received, for example, through the GUI 111; transmit ahost signature to POS 114 in response to at least a transactionchallenge; store, at least in part, details of the transaction executedbetween place between the card 112 and the POS device 114; generateand/or present alerts (e.g., audio-visual alerts) to the user throughthe GUI 111; generate and/or transmit wireless-message alerts to thefinancial institution 106 using the mobile device 110 if cellularcapable; and/or others. In some implementations, the transaction card112 may include a communication module with of a protocol translationmodule, antenna tuning circuit, power circuit and a miniature antennatuned to exchange wireless data with a retail terminal 114.

In some implementations, the transaction card 112 may initiate atransaction in response to at least a user selecting a graphical elementin the GUI 111. The transaction card 112 may initiate a transaction withthe POS 114 in response to at least wireless request transmitted by thePOS 114. In some implementations, the transaction card 112 mayselectively switch the antenna between an on and off state in responseto one or more events. The one or more events may include a userrequest, completion of transaction, insertion of card 112 in a differentmobile device, location change, timer events, detection of incorrect PINentered by the user, change of wireless network that the device isconnected to, message received from the financial institution 106 usingwireless communication methods such as SMS, and/or other events. Forexample, the transaction card 112 may receive one or more commands toswitch the antenna off from a cellular network (not illustrated) throughthe mobile device 110. In some implementations, the transaction card 112may request user identification such as a PIN, a user ID and passwordcombination, biometric signature, and/or others.

In regards to translating between protocols, the transaction card 112may process information in, for example, ISO 7816, a standard securityprotocol, and/or others. In this case, the transaction card 112 maytranslate between an NFC protocol (e.g., ISO 18092) and thetransaction-card protocol. In some implementations, ISO 7816 commandsmay be encapsulated within interface commands used to transmit databetween the host device 114 and the card 112. In addition, thetransaction card 112 may interface the mobile device 110 through aphysical interface such as MicroSD, Mini-SD SD, MMC, miniMMC, microMMC,USB, miniUSB, microUSB, firewire, APPLE iDock, and/or others. In regardto security processes, the transaction card 112 may implement one ormore encryption algorithms to secure transaction information such ascard number (e.g., credit card number, debit-card number, bank accountnumber), PIN, and/or other security related information. The securityrelated information may include an expiry date, card verification code,user name, home phone number, user zip code and/or other userinformation associated with verifying an identity of the card holder. Insome implementations, the transaction card 112 may execute private key(symmetric algorithms) such as DES, TDES and/or others or public key(asymmetric algorithms) such as RSA, elliptic curves, and/or others. Inaddition, the transaction card 112 may include memory (e.g., Flash,EEPROM) for storing user data, applications, offline Webpages, and/orother information. In regards to applications, the transaction card 112may execute a locally stored application and present information to andreceived information from the user through the GUI 111. For example, thetransaction card 112 may execute an application used to synchronize anaccount balance with the financial institution 106 using the GUI 111 andthe mobile device 110. Alternatively or in addition to applications, thetransaction card 112 may present offline Web pages to the user using theGUI 111. In response to initiating a transaction, the transaction card112 may automatically present an offline Web page through the GUI 111.In some implementations, the offline Web page can be associated with afinancial institution 106. In some implementations, the transaction card112 can be backward compatible and operate as a mass storage device. Forexample, if the wireless interface of the transaction card 112 is notavailable or deactivated, the transaction card 112 may operate as a massstorage device enabling users to access data stored in the memorycomponent (e.g., Flash). In some implementations, the transaction card112 can execute a set of initialization commands in response to at leastinsertion into the mobile device 110. These initialization commands mayinclude determining device related information for the mobile device 100(e.g., phone number, signature, connected network information, locationinformation and other available properties), determining user relatinginformation (e.g., PIN code, activation code), incrementing counters,setting flags and activating/deactivating functions according topre-existing rules and/or algorithms.

In some implementations, the transaction card 112 may automaticallyexecute one or more fraud control processes. For example, thetransaction card 112 may identify an operational change andautomatically transmit a notification to the financial institutionbased, at least in part, on the identified change. The transaction card112 may execute two fraud control processes: (1) determine a violationof one or more rules; and (2) automatically execute one or more actionsin response to at least the violation. In regards to rules, thetransaction card 112 may locally store rules associated with updates tooperational aspects of the transaction card 112. For example, thetransaction card 112 may store a rule indicating a change in mobile hostdevice 110 is an operational violation. In some implementations, thetransaction card 112 may store rules based, at least in part, on updatesto one or more of the following: phone number of host device 110; MACaddress of host device 110; network wirelessly connected to host device110; location of host device; and/or other aspects. In response to oneor more events matching or otherwise violating rules, the transactioncard 112 may execute one or more processes to substantially prevent orotherwise notify the financial institutions 106 of potentiallyfraudulent activity. For example, the transaction card 112 may execute acommand to block an associated user account and/or the transaction card112. Alternatively or in addition, the transaction card 112 may transmita command to the financial institution 106 to call the mobile hostdevice 110. In some implementations, the transaction card 112 mayexecute a command based, at least in part, on an event type. In someexamples, the transaction card 112 may initiate a call with thefinancial institution 106 in response to at least a change in number ofthe host device 110. In some examples, the transaction card 112 mayre-execute an activation process in response to at least a specifiedevent type. An activation process may include activating the transactioncard and/or financial account as discussed in more detail with respectto FIG. 9. In some implementations, the transaction card 112 may executea command to disconnect the GUI 111 from the transaction card 112. Thetransaction card 112 may present a disconnection notification throughthe GUI 111 prior to executing the command. In some implementations, thetransaction card 112 may transmit a command to the financial institution106 to deactivate an account associated with the card 112.

In some implementations, the POS 114 may transmit a transaction request117 to the transaction card 112 for information to generate anauthorization request 118. In response to at least the transactionrequest, the transaction card 112 may transmit one or more transactionresponses 119 identifying information associated with a payment account.In some implementations, the POS device 114 may transmit a request 118to authorize a transaction to the financial institution 106. Theauthorization information may include an account number, a transactionamount, user credentials, and/or other information. In response to atleast the transaction request 118, the financial institution 106 maytransmit an authorization response 120 to the POS device 114. In someimplementations, the POS device 114 may transmit the response 120 to thetransaction card 112. The transaction response 120 may include, forexample, a receipt presentable to the user through the GUI 111 a. Insome implementations, the financial institution 106 may transmit theauthorization response 120 to the mobile device through a cellular corenetwork (see FIG. 2). In this implementation, the financial institution106 may have stored the association between the mobile device 110 andthe transaction card 112 during the user sign-up process, automaticallyupon user activation of the card 112 when, for example, the card 112 isinitially inserted into the mobile device 110, and/or other event. Inthe illustrated implementation, the POS 114 includes the GUI 109.

The GUI 109 comprises a graphical user interface operable to allow theuser of the POS 114 to interface with at least a portion of the system100 for any suitable purpose, such as a user entering transactioninformation (e.g., PIN, transaction acceptance) and/or and presentingtransaction information (e.g., transaction amount). Generally, the GUI109 provides the particular user with an efficient and user-friendlypresentation of data provided by or communicated within the system 100and/or also an efficient and user-friendly means for the user toinitiate a wirelessly transaction with the transaction card 112. The GUI109 may present a series of screens or displays to the user to, forexample, accept a transaction and enter security information such as aPIN.

In some implementations, the transaction card 112 can be implementeddifferently. The transaction card 112 may be implemented as a KeyFOB andremains live outside the mobile device 110 as a FOB. In this case, thetransaction card 112 may be passive and powered from an inductionmagnetic field generated by the POS 114. The transaction card 112 may beimplemented in the form of an industrial integrated circuit chip formounting on a PCB or IC chip. In some implementations, the transactioncard 112 may be implemented in the form of a self contained desktopstandalone unit powered by external AC adapter or stand alone box. Insome implementations, the transaction card 112 can be implemented as anexternal attachment to a mobile device 110 (e.g., case) and connected tothe mobile device using a peripheral interface such as USB, serial port,the iDock APPLE proprietary interface, and/or other interface.

In some implementations, the transaction card 112 may operate inaccordance with one or more of the following modes: active cardemulation; active reader; self train; killed; memory; inactive; and/orother modes. The transaction card 112 may operate active-card-emulationmode to convert the mobile device 110 to a contactless payment deviceloaded with a financial vehicle (FV) that may be, for example, a creditcard, a debit card, a gift card and/or other retail payment product. Inthis mode, the transaction card 112 may execute payment transactions atany capable retail payment terminal (e.g., POS 114) that acceptscontactless payment transactions. For example, such terminals may becontactless-enabled terminals currently being deployed by merchantsunder MasterCard's paypass, Visa's paywave programs, Amex ExpressPay,Discover Zip, and/or other payment programs. After the antenna of thetransaction card 112 is activated in this mode, a merchant terminal maydetect the presence of a host device with the transaction card 112 andprompt the user to authorize a transaction such as by entering a PIN,signing on a terminal interface, confirming the amount of thetransaction, and/or other action. In this mode, such transactions may behandled as a normal card-present transaction. In other words, the POS114 may perceive the transaction card 112 as a contactless plasticpayment card and may communicate with the transaction card 112 as acontactless plastic payment card to execute payment transactions. Inthese implementations when the card 112 operates in an active-cardemulation mode, the POS 114 can wirelessly communicate with thetransaction card 112 using the same signals used to communicate with acontactless plastic payment card. In this active-card emulation mode,the transaction card 112 emulates a contactless plastic payment card andmay be backward compatible with the POS 114. In this implementation,neither the terminal nor the financial institution may requireadditional software to execute the transaction. In addition, thetransaction card 112 in this mode may be used for other applicationssuch as physical access control (to open gates either in a corporateenvironment or in a transit environment), logical access control (torequest network access via a PC), application access control (to buyaccess for amenities such as transportation, movies or wherever paymentneeds to be made to gain access to a facility), and/or otherapplications.

In the active-reader mode, the transaction card 112 may convert themobile device 110 to a contactless reader device capable of receivingdata when in range of a transmitting terminal (e.g., POS 114). In someimplementations, this mode can require special NFC hardware with readermode capability as part of the transaction card 112. In the event thatthe mobile device 110 is proximate (e.g., 10 cm or less) a transmittingterminal, the reader mode of the transaction card 112 may activated andprompt the user for authorization to receive data through the GUI 111.This mode may only be suitable for mobile devices 110 with a UI element,such as an OK button and a screen, an LED to indicate that datareception is being requested, and/or other interfaces. Once the userauthorizes the transmission, the transaction card 112 in this mode mayreceive, and locally store, process and may execute a transaction and/orforward received data to another entity. For example, the transactioncard 112 in this mode may receive content through promotional posters,validating the purchase of a ticket, and/or others. For example, thetransaction card 112 in this mode may function as a mobile POS terminalreceiving transaction information from a plastic contactless card/FOBand instructing the POS 114 to prepare a transaction authorizationrequest for the financial institution 106 through a cellular corenetwork. Once the financial institution 106 authorizes the transaction,the mobile device 110 may display the confirmation of the transaction tothe user through the GUI 111.

In regards to the self-train mode, the transaction card 112 may executea version of the reader mode. In some implementations, the self-trainmode can be activated by a special action (e.g., a needle point press toa small switch, entry of an administrative password via the GUI 111). Inresponse to at least activating this mode, the transaction card 112 maybe configured to receive personalization data over, for example, theshort range wireless interface from another peer transaction card suchas the plastic contactless cards compliant with this functionality andissued by the financial institution 106 or a specially preparedadministrative card for this purpose. Personalization data received inthis mode may include encrypted FV information that is stored in securedmemory of the transaction card 112. In some implementations, thetransaction card 112 in this mode may receive the FV information througha contactless interface of a transmitter and/or others. The transactioncard 112 may then synthesize the FV information that corresponds to theuser account and personalize an internal security module that includes,for example, payment applications for executing transactions withfinancial institutions 106 and associated user credentials. Theself-train mode may be used to re-personalize the transaction card 112in the field. In some implementations, all previous data can be deletedif the self-train mode is activated. The self-train mode may be apeer-to-peer personalization mode where the card 112 may receivepersonalization information from another transaction card 112. This modemay represent an additional personalization mode as compared withfactory, store and/or Over-The-Air (OTA) personalization scenarios whichmay be server to client personalization scenarios. In someimplementations, the self-train mode may be a peer-to-peerpersonalization mode where the transaction card 112 receivespersonalization information from another transaction card. Since twotransaction cards 112 are used in this mode, this mode may be differentfrom a server-to-client personalization scenario as with a factory,store, and OTA personalization.

In regards to the inactive mode, the transaction card 112 maytemporarily deactivate the contactless interface. In someimplementations, the inactive mode can be activated through the physicalinterface with the mobile device 110 such as a microSD interface. Inresponse to at least the activation of the inactive mode, thetransaction card 112 may temporarily behave as only a mass-memory card.In some implementations, the card 112 may also enter this state when thereset needle point is pressed. In this mode, the transaction card 112may preserve locally-stored information including financial user data.In this mode, the transaction card 112 may execute the activationprocess and if successful may return to the active mode. Financialinstitutions 106 may use this mode to temporarily prevent usage inresponse to at least identifying at least potentially fraudulentactivity.

In regards to the killed mode, the transaction card 112 may permanentlydeactivate the contactless interface. In some implementations, thekilled mode is activated through the physical interface with the mobiledevice 110 such as a microSD interface. In response to at least theactivation of the killed mode, the transaction card 112 may permanentlybehaves as a mass memory stick. In the event that the reset needle pointis pressed, the transaction card 112 may, in some implementations, notbe made to enter any other modes. In addition, the transaction card 112may delete financial content in memory in response to at least this modebeing activated. In some implementations, financial institutions 106 mayuse this mode to delete data from a transaction card 112 that isphysically lost but still connected to the wireless network via the hostdevice 110.

In regards to the memory mode, the transaction card 112 may operate as amass memory stick such that the memory is accessible throughconventional methods. In some implementations, the transaction card 112may automatically activate this mode in response to at least beingremoved from the host device, inserted into a non-authorized hostdevice, and/or other events. The transaction card 112 may be switched toactive mode from the memory mode by, for example, inserting the card 112into an authorized device or may be switched from this mode into theself-train mode to re-personalize the device for a new host device or anew user account. In some implementations, the memory mode may operatesubstantially same as the inactive mode.

In some implementations, the transaction card 112 may bere-personalized/updated such as using software device management processand/or a hardware reset. For example, the user may want tore-personalize the transaction card 112 to change host devices, to havemultiple host devices, and/or other reasons. In regards to the softwaredevice management, the user may need to cradle the new host device withthe transaction card 112 inserted to launch the software devicemanagement application. In some implementations, the software managementapplication can be an application directly installed on the client 104,integrated as a plug-in to a normal synchronization application such asActiveSync, available via a browser plug-in running on the plug-inprovider's website, and/or other sources. The user may log into theapplication and verify their identity, and in response to verification,the application may allow access to a devices section in the devicemanagement application. The device management application may read thetransaction card 112 and display the MAC addresses, signatures of thedevices that he has inserted his plug-in to, and/or other devicespecific information. The mobile device 110 may be marked as active andthe host device may be shown as disallowed or inactive. The applicationmay enable the user to update the status of the new host device, and inresponse to at least the selection, the device management applicationmay install the signature on the new host device and mark update thestatus as allowable in secure memory of the transaction card 112. Theuser may be able to also update the status of the mobile device 110 todisallowed. Otherwise, both devices may be active and the transactioncard 112 may be switched between the two devices. In regards to thehardware reset process, the use may use the reset needle point press onthe physical transaction card 112 to activate the self-train mode. Inthis mode, the financial data may be deleted and have to be reloaded.When the transaction card 112 is inserted into the new host device, theprovisioning process may begin as discussed above.

The POS 114 can include any software, hardware, and/or firmware thatreceives from the transaction card 112 account information for executinga transaction with one or more financial institutions 106. For example,the POS 114 may be an electronic cash register capable of wirelesslycommunicating transaction information with the transaction card 112 a.The POS 114 may communicate transaction information associated withtraditional contact payment methods such as plastic cards and checks. Ifenabled for wireless/contactless payment transactions, the POS 114 maycommunicate information with the transaction card 112 in one or more thefollowing formats: 14443 Type A/B, Felica, MiFare, ISO 18092, ISO 15693;and/or others. The transaction information may include verificationinformation, check number, routing number, account number, transactionamount, time, driver's license number, merchant ID, merchant parameters,credit-card number, debit-card number, digital signature and/or otherinformation. In some implementations, the transaction information may beencrypted. In illustrated implementation, the POS 114 can wirelesslyreceive encrypted transaction information from the transaction card 112and electronically send the information to one or more of the financialinstitutions 106 for authorization. For example, the POS 114 may receivean indication that a transaction amount has been accepted or declinedfor the identified account and/or request additional information fromthe transaction card 112.

As used in this disclosure, the client 104 are intended to encompass apersonal computer, touch screen terminal, workstation, network computer,a desktop, kiosk, wireless data port, smart phone, PDA, one or moreprocessors within these or other devices, or any other suitableprocessing or electronic device used for viewing transaction informationassociated with the transaction card 112. For example, the client 104may be a PDA operable to wirelessly connect with an external orunsecured network. In another example, the client 104 may comprise alaptop that includes an input device, such as a keypad, touch screen,mouse, or other device that can accept information, and an output devicethat conveys information associated with transactions executed with thefinancial institutions 106, including digital data, visual information,or GUI 115. In some implementations, the client 104 b can wirelesslycommunicate with the transaction card 112 b using, for example, an NFCprotocol. In some implementations, the client 104 a includes a cardreader 116 having a physical interface for communicating with thetransaction card 112 c. In some implementations, the card reader 116 mayat least include an adapter 116 b that adapts the interface supported bythe client 104 (e.g., USB, Firewire, Bluetooth, WiFi) to the physicalinterface supported by the card 112 (e.g., SD/NFC). In this case, theclient 104 a may not include a transceiver for wireless communication.

The GUI 115 comprises a graphical user interface operable to allow theuser of the client 104 to interface with at least a portion of thesystem 100 for any suitable purpose, such as viewing transactioninformation. Generally, the GUI 115 provides the particular user with anefficient and user-friendly presentation of data provided by orcommunicated within the system 100. The GUI 115 may comprise a pluralityof customizable frames or views having interactive fields, pull-downlists, and/or buttons operated by the user. The term graphical userinterface may be used in the singular or in the plural to describe oneor more graphical user interfaces and each of the displays of aparticular graphical user interface. The GUI 115 can include anygraphical user interface, such as a generic web browser or touch screen,that processes information in the system 100 and presents the results tothe user. The financial institutions 106 can accept data from the client104 using, for example, the web browser (e.g., Microsoft InternetExplorer or Mozilla Firefox) and return the appropriate responses (e.g.,HTML or XML) to the browser using the network 108. In someimplementations, the GUI 111 c of the transaction card 112 c may bepresented through the GUI 115 a of the client 104 a. In theseimplementations, the GUI 115 a may retrieve user credentials from theGUI 111 c and populate financial forms presented in the GUI 115 a. Forexample, the GUI 115 a may present a forum to the user for enteringcredit card information to purchase a good through the Internet, and theGUI 115 a may populate the form using the GUI 111 c in response to atleast a request from the user.

Financial institutions 106 a-c can include any enterprise that mayauthorize transactions received through the network 108. For example,the financial institution 106 a may be a credit card provider thatdetermines whether to authorize a transaction based, at least in part,on information received through the network 106. The financialinstitution 106 may be a credit card provider, a bank, an association(e.g., VISA), a retail merchant (e.g., Target), a prepaid/gift cardprovider, an internet bank, and/or others. In general, the financialinstitution 106 may execute one or more of the following: receive arequest to authorize a transaction; identify an account number and othertransaction information (e.g., PIN); identify funds and/or a creditlimit associated with the identified account; determine whether thetransaction request exceeds the funds and/or credit limit and/orviolates any other rules associated with the account; transmit anindication whether the transaction has been accepted or declined; and/orother processes. In regards to banking, the financial institution 106may identify an account number (e.g., bank account, debit-card number)and associated verification information (e.g., PIN, zip code) anddetermine funds available to the account holder. Based, at least inpart, on the identified funds, the financial institution 106 may eitheraccept or reject the requested transaction or request additionalinformation. As for encryption, the financial institution 106 may use apublic key algorithm such as RSA or elliptic curves and/or private keyalgorithms such as TDES to encrypt and decrypt data.

Network 108 facilitates wireless or wired communication between thefinancial institutions and any other local or remote computer, such asclients 104 and the POS device 114. Network 108 may be all or a portionof an enterprise or secured network. While illustrated as singlenetwork, network 108 may be a continuous network logically divided intovarious sub-nets or virtual networks without departing from the scope ofthis disclosure, so long as at least a portion of network 108 mayfacilitate communications of transaction information between thefinancial institutions 106, the clients 104, and the offline store 102.In some implementations, network 108 encompasses any internal orexternal network, networks, sub-network, or combination thereof operableto facilitate communications between various computing components insystem 100. Network 108 may communicate, for example, Internet Protocol(IP) packets, Frame Relay frames, Asynchronous Transfer Mode (ATM)cells, voice, video, data, and other suitable information betweennetwork addresses. Network 108 may include one or more local areanetworks (LANs), radio access networks (RANs), metropolitan areanetworks (MANs), wide area networks (WANs), all or a portion of theglobal computer network known as the Internet, and/or any othercommunication system or systems at one or more locations.

FIG. 2 is a block diagram illustrating an example transaction system 200for wirelessly communicating transactions information using cellularradio technology. For example, the system 200 may wirelessly communicatea transaction receipt to a transaction card 112 using a mobile hostdevice 110 and cellular radio technology. In some implementations,cellular radio technology may include Global System for MobileCommunication (GSM), Code Division Multiple Access (CDMA), UniversalMobile Telecommunications System (UMTS), and/or any other cellulartechnology. The financial institutions 106 may assign one or more mobilehost devices 110 to a transaction card 112 in response to one or moreevents. In some examples, the user may register the one or more mobiledevices 110 with the financial institution 106 in connection with, forexample, requesting the associated transaction card 112. In someexamples, the transaction card 112 may register the mobile host device110 with the financial institution 106 in response to at least aninitial insertion into the device 110. Regardless of the associationprocess, the system 100 may use the cellular capabilities of the hostdevices 110 to communicate information between the financialinstitutions 106 and the transaction card 112. In using the cellularradio technology of the host device 110, the system 100 may communicatewith the transaction card 112 when the card 112 is not proximate aretail device, such as the POS device 114 of FIG. 1.

In the illustrated implementation, the cellular core network 202typically includes various switching elements, gateways and servicecontrol functions for providing cellular services. The cellular corenetwork 202 often provides these services via a number of cellularaccess networks (e.g., RAN) and also interfaces the cellular system withother communication systems such as the network 108 via a MSC 206. Inaccordance with the cellular standards, the cellular core network 202may include a circuit switched (or voice switching) portion forprocessing voice calls and a packet switched (or data switching) portionfor supporting data transfers such as, for example, e-mail messages andweb browsing. The circuit switched portion includes MSC 206 thatswitches or connects telephone calls between radio access network (RAN)204 and the network 108 or another network, between cellular corenetworks or others. In case the core network 202 is a GSM core network,the core network 202 can include a packet-switched portion, also knownas General Packet Radio Service (GPRS), including a Serving GPRS SupportNode (SGSN) (not illustrated), similar to MSC 206, for serving andtracking communication devices 102, and a Gateway GPRS Support Node(GGSN) (not illustrated) for establishing connections betweenpacket-switched networks and communication devices 110. The SGSN mayalso contain subscriber data useful for establishing and handing overcall connections. The cellular core network 202 may also include a homelocation register (HLR) for maintaining “permanent” subscriber data anda visitor location register (VLR) (and/or an SGSN) for “temporarily”maintaining subscriber data retrieved from the HLR and up-to-dateinformation on the location of those communications devices 110 using awireless communications method. In addition, the cellular core network202 may include Authentication, Authorization, and Accounting (AAA) thatperforms the role of authenticating, authorizing, and accounting fordevices 110 operable to access GSM core network 202. While thedescription of the core network 202 is described with respect to GSMnetworks, the core network 202 may include other cellular radiotechnologies such as UMTS, CDMA, and others without departing from thescope of this disclosure.

The RAN 204 provides a radio interface between mobile devices and thecellular core network 202 which may provide real-time voice, data, andmultimedia services (e.g., a call) to mobile devices through a macrocell208. In general, the RAN 204 communicates air frames via radio frequency(RF) links. In particular, the RAN 204 converts between air frames tophysical link based messages for transmission through the cellular corenetwork 202. The RAN 204 may implement, for example, one of thefollowing wireless interface standards during transmission: AdvancedMobile Phone Service (AMPS), GSM standards, Code Division MultipleAccess (CDMA), Time Division Multiple Access (TDMA), IS-54 (TDMA),General Packet Radio Service (GPRS), Enhanced Data Rates for GlobalEvolution (EDGE), or proprietary radio interfaces. Users may subscribeto the RAN 204, for example, to receive cellular telephone service,Global Positioning System (GPS) service, XM radio service, etc.

The RAN 204 may include Base Stations (BS) 210 connected to Base StationControllers (BSC) 212. BS 210 receives and transmits air frames within ageographic region of RAN 204 (i.e. transmitted by a cellular device 102e) and communicates with other mobile devices 110 connected to the GSMcore network 202. Each BSC 212 is associated with one or more BS 210 andcontrols the associated BS 210. For example, BSC 212 may providefunctions such as handover, cell configuration data, control of RF powerlevels or any other suitable functions for managing radio resource androuting signals to and from BS 210. MSC 206 handles access to BSC 212and the network 108. MSC 206 may be connected to BSC 212 through astandard interface such as the A-interface. While the elements of RAN204 are describe with respect to GSM networks, the RAN 204 may includeother cellular technologies such as UMTS, CDMA, and/or others. In thecase of UMTS, the RAN 204 may include Node B and Radio NetworkControllers (RNC).

The contactless smart card 214 is a pocket-sized card with embeddedintegrated circuits that process information. For example, the smartcard 214 may wirelessly receive transaction information, process theinformation using embedded applications and wirelessly transmit aresponse. The contactless smart card 214 may wirelessly communicate withcard readers through RFID induction technology at data rates of 106 to848 kbit/s. The card 214 may wirelessly communicate with proximatereaders between 10 cm (e.g., ISO/IEC 14443) to 50 cm (e.g., ISO 15693).The contactless smart card 214 operates independent of an internal powersupply and captures energy from incident radio-frequency interrogationsignals to power the embedded electronics. The smart card 214 may be amemory card or microprocessor card. In general, memory cards includeonly non-volatile memory storage components and may include somespecific security logic. Microprocessor cards include volatile memoryand microprocessor components. In some implementations, the smart card214 can have dimensions of normally credit card size (e.g.,85.60×53.98×0.76 mm, 5×15×0.76 mm). In some implementations, the smartcard 214 may be a fob or other security token. The smart card 214 mayinclude a security system with tamper-resistant properties (e.g., asecure cryptoprocessor, secure file system, human-readable features)and/or may be configured to provide security services (e.g.,confidentiality of stored information).

In some aspects of operation, the financial institution 106 may use themobile host device 110 to communicate information to the transactioncard 112. For example, the financial institution 106 may wirelesslycommunicate with the mobile host device 110 using the cellular corenetwork 202. In some implementations, the financial institution 106 maytransmit information to the mobile host device 110 in response to atleast an event. The information may include, for example, transactioninformation (e.g., transaction receipt, transaction history), scripts,applications, Web pages, and/or other information associated with thefinancial institutions 106. The event may include completing atransaction, determining a transaction card 112 is outside the operatingrange of a POS terminal, receiving a request from a user of the mobilehost device, and/or others. For example, the financial institution 106may identify a mobile host device 110 associated with a card 112 thatexecuted a transaction and transmit transaction information to themobile host device 110 using the cellular core network 202. In using thecellular core network 202, the financial institutions 106 may transmitinformation to the transaction card 112 without requiring a POS terminalbeing proximate to the card 112. In addition or alternatively, thefinancial institution 106 may request information from the mobile hostdevice 110, the transaction card 112 and/or the user using the cellularcore network 202. For example, the financial institution 106 maytransmit a request for transaction history to the card 112 through thecellular core network 202 and the mobile host device 110.

In some aspects of operation, a merchant or other entity may operate themobile host device 110 c as a mobile POS terminal configured towirelessly execute transactions with the smart card 214. For example, avendor may be mobile (e.g., a taxi driver) and may include a mobile hostdevice 110 c with a transaction card 112 c. In this example, thetransaction card 112 c may wirelessly receive account information fromthe smart card 214 and the POS 114 may transmit an authorization requestto the financial institution 106 using the mobile host device 110 andthe cellular core network 202. In response to at least the request, thefinancial institution 106 may generate an authorization response to thetransaction card 112 c using the mobile host device 110 and the cellularnetwork 202.

In some implementations, the system 100 may execute one or more of themodes discussed with respect to FIG. 1. For example, the transactioncard 112 may be re-personalized/updated using the cellular radiotechnology of the mobile host device 110. The user may want tore-personalize the transaction card 112 to change host devices, to havemultiple host devices, and/or other reasons. In regards to the softwaredevice management, the user may transmit to the financial institution106 a request to re-personalize the transaction card 112 using thecellular radio technology of the host device 110.

FIG. 3 illustrates is a block diagram illustrating an exampletransaction card 112 of FIG. 1 in accordance with some implementationsof the present disclosure. In general, the transaction card 112 includespersonalized modules that execute financial transactions independent ofthe mobile device 110. The illustrated transaction card 112 is forexample purposes only, and the transaction card 112 may include some,all or different modules without departing from the scope of thisdisclosure.

In some implementations, the transaction card 112 can include aninterface layer 302, an API/UI 304, a Web server 306, a real-timeframework 308, payment applications 310, value added applications 312,user credentials 314, real-time OS 316, contactless chipset 318, antennacontrol functions 320, antenna 322, bank used memory 324, and freememory 326. In some implementations, a host controller includes theinterface layer 302, the API/UI 304, the Web server 306, the real-timeframework 308, the contactless chipset 318, and the antenna controlfunctions 320. In some implementations, a security module includes thepayment applications 310 and the user credentials 314. The bank usedmemory 324 and free memory 326 may be contained in Flash. In someimplementations, the contactless chipset 318 may be integrated withinthe security module or operated as a standalone. The antenna 322 may beelectronic circuitry.

The interface layer 302 includes interfaces to both the host device,i.e., physical connection, and the external world, i.e.,wireless/contactless connection. In payment implementations, thewireless connection can be based on any suitable wireless standard suchas contactless (e.g., ISP 14443 A/B), proximity (e.g., ISO 15693), NFC(e.g., ISO 18092), and/or others. In some implementations, the wirelessconnection can use another short range wireless protocol such asBluetooth, another proprietary interfaces used by retail paymentterminals (Felica in Japan, MiFare in Asia, etc.), and/or others. Inregards to the physical interface, the interface layer 302 mayphysically interface the mobile device 110 using an SD protocol such asMicroSD, Mini-SD or SD (full-size). In some implementations, thephysical interface may include a converter/adapter to convert betweentwo different protocols based, at least in part, on the mobile device110. In some implementations, the mobile device 110 may communicateusing protocols such as USB, MMC, iPhone proprietary interface, orothers.

The API/UI layer 304 can include any software, hardware, and/or firmwarethat operates as an API between the mobile device 110 and thetransaction card 112 and as the GUI 111. Prior to executingtransactions, the transaction card 112 may automatically install driversin the mobile device 110 in response to at least insertion. For example,the transaction card 112 may automatically install a MicroSD devicedriver in the device 110 to enable the transaction card 112 to interfacethe mobile device 110. In some implementations, the transaction card 112may install an enhanced device driver such as a Mass Memory with Radio(MMR) API. In this implementation, the interface can drive a class ofplug-ins that contain mass memory as well as a radio interface. The MMRAPI may execute one or more of the following: connect/disconnect to/fromthe MMR controller (Microcontroller in the plug-in); transfer data usingMM protocol (e.g., SD, MMC, XD, USB, Firewire); send encrypted data tothe MMR controller; receive Acknowledgement of Success or Error;received status word indicating description of error; turn radio on/off;send instruction to the transaction card 112 to turn the antenna on withspecifying the mode of operation (e.g., sending mode, listening mode);transmit data such as send instruction to controller to transmit datavia the radio; listen for data such as send instruction to controller tolisten for data; read data such as send instruction to controller tosend the data received by the listening radio; and/or others. In someimplementations, MMR can be compliant with TCP/IP. In someimplementations, API encapsulated ISO 7816 commands may be processed bythe security module in addition to other commands.

In some implementations, the API can operate in accordance with the twoprocesses: (1) the transaction card 112 as the master and the mobiledevice 110 as the slave; and (2) the card UI as the master. In the firstprocess, the transaction card 112 may pass one or more commands to themobile device 110 in response to, for example, insertion of thetransaction card 112 into a slot in the mobile device 110, a transactionbetween the transaction card 112 and the POS 114, and/or other events.In some implementations, the transaction card 112 can request the mobiledevice 110 to execute one or more of following functions: Get UserInput; Get Signature; Display Data; Send Data; Receive Data; and/orothers. The Get User Input command may present a request through the GUI111 for data from the user. In some implementations, the Get User Inputmay present a request for multiple data inputs. The data inputs may beany suitable format such as numeric, alphanumeric, and/or other stringsof characters. The Get Signature command may request the mobile device110 to return identification data such as, for example, a phone number,a device ID like an IMEI code or a MAC address, a network code, asubscription ID like the SIM card number, a connection status, locationinformation, Wi-Fi beacons, GPS data, and/or other device specificinformation. The Display Data command may present a dialog to the userthrough the GUI 111. In some implementations, the dialog can disappearafter a period of time, a user selection, and/or other event. The SendData command may request the mobile device 110 to transmit packet datausing its own connection to the external world (e.g., SMS, cellular,Wi-Fi). The Receive Data command may request the mobile device 110 toopen a connection channel with certain parameters and identify datareceived through the connection. In some implementations, the commandcan request the mobile device 110 to forward any data (e.g., SMS)satisfying certain criteria to be forwarded to the transaction card 112.

In regards to the UI as master, the UI may execute one or more of thefollowing commands: security module Command/Response;Activate/Deactivate; Flash Memory Read/Write; Send Data with or withoutencryption; Receive Data with or without decryption; URL Get Data/URLPost Data; and/or others. The security module commands may relate tosecurity functions provided by the card and are directed towards thesecurity module within the transaction card 112 (e.g., standard ISO 7816command, proprietary commands). In some implementations, the commandsmay include encryption, authentication, provisioning of data, creationof security domains, update of security domain, update of usercredentials after verification of key, and/or others. In someimplementations, the commands may include non security related smartcard commands such as, for example, read transaction history commands.The read transaction history command may perform a read of the securememory 324 of the transaction card 112. In some implementations, certainflags or areas of the secure memory 324 may be written to after securityverification. The Activate/Deactivate command may activate or deactivatecertain functions of the transaction card 112. The Flash MemoryRead/Write command may execute a read/write operation on a specifiedarea of the non-secure memory 326. The Send Data with or withoutencryption command may instruct the transaction card 112 to transmitdata using its wireless connection with, for example, the POS 114. Inaddition, the data may be encrypted by the transaction card 112 prior totransmission using, for example, keys and encryption capability storedwithin the security module. The Receive Data with or without decryptioncommand may instruct the transaction card 112 to switch to listeningmode to receive data from its wireless connection with theterminal/reader (e.g., POS 114). In some implementations, datadecryption can be requested by the security module using, for example,keys and decryption algorithms available on the security module, i.e.,on-board decryption. The URL Get Data/URL Post Data command may instructthe web server 306 to return pages as per offline get or postinstructions using, for example, offline URLs.

The Web server 306, as part of the OS of the transaction card 112, mayassign or otherwise associate URL style addressing to certain filesstored in the memory 326 (e.g., flash) of the transaction card 112. Insome implementations, the Web server 306 locates a file using the URLand returns the file to a browser using standard HTTP, HTTPS styletransfer. In some implementations, the definition of the files can beformatted using standard HTML, XHTML, WML and/or XML style languages.The file may include links that point to additional offline storagelocations in the memory 326 and/or Internet sites that the mobile device110 may access. In some implementations, the Web server 306 may supportsecurity protocols such as SSL. The Web server 306 may transfer anapplication in memory 326 to the mobile device 111 for installation andexecution. The Web server 306 may request the capabilities of thebrowser on the device 110 using, for example, the browser user agentprofile, in order to customize the offline Web page according to thesupported capabilities of the device and the browser, such as, forexample, supported markup language, screen size, resolution, colors andsuch.

As part of the Real time OS, the real-time framework 308 may execute oneor more functions based, at least in part, on one or more periods oftime. For example, the real-time framework 308 may enable an internalclock available on the CPU to provide timestamps in response to at leastrequested events. The real-time framework 308 may allow certain tasks tobe pre-scheduled such that the tasks are executed in response to atleast certain time and/or event based triggers. In some implementations,the real-time framework 308 may allow the CPU to insert delays incertain transactions. In some implementation, a part of WAP standardscalled WTAI (Wireless Telephone Application Interface) can beimplemented to allow offline browser pages on the card 112 to make useof functions offered by the mobile device 110 (e.g., send/receivewireless data, send/receive SMS, make a voice call, play a ringtoneetc.).

The payment applications 310 can include any software, hardware, and/orfirmware that exchanges transaction information with the retail terminalusing, in some instances, a pre-defined sequence and/or data format. Forexample, the payment applications 310 may generate a response to atransaction request by selecting, extracting or otherwise including usercredentials in the response, in a format compatible with the retailterminal's payment processing application. In some implementations, thepayment applications 310 may execute one or more of the following:transmit properties of the transaction card 112 in response to at leastan identification request received from the POS 114; receive a requestto execute a transaction from, for example, the POS 114; identify usercredentials in the bank-used memory 324 in response to at least therequest; generate a transaction response based, at least in part, on theuser credentials; transmit the transaction response to the POS 114using, for example, a contactless chipset; receive clear data, forexample a random number, from the POS 114 and provide a responsecontaining encrypted data by encrypting the clear data using thecryptographic capabilities of the secure element; transmit the encrypteddata using the contactless chipset 318; increment a transaction counterwith every transaction request received; transmit a value of thetransaction counter in response to a request from the POS 114; storedetails of the transaction request received from the POS 114 into thetransaction history area of the bank used memory 324; transmittransaction history to the CPU of the intelligent card 112 in responseto such a request; receive ISO 7816 requests from the CPU of theintelligent card 112; execute corresponding transactions using thesecure element OS; provide responses back to the CPU; and/or otherprocesses. In generating the transaction response, the paymentapplication 310 may generate the response in a format specified by thepayment network (VISA, MasterCard, Amex, Discover) associated with afinancial institution 106 or a proprietary format owned and defined bythe financial institution 106 and processable by the POS 114. Thetransaction request may include one or more of the following: usercredentials (e.g., account number); expiry data, card verificationnumbers; a transaction count; and/or other card or user information. Insome implementations, the payment application 310 may comprises abrowser application to enable transactions. The browser application 310may be a browser that may be installed if the device 110 is eithermissing a browser or has a browser that is incompatible with the Webserver 306 on the card 112. After installation of such browser 310,future communications between the mobile device 110 and the web-server306 make use the newly installed browser.

The real-time OS 316 may execute or otherwise include one or more of thefollowing: real-time framework 308; a host process that implements thephysical interface between the transaction-card CPU and the mobiledevice 110; an interface that implements the physical interface betweenthe transaction-card CPU and the security module; a memory-managementprocess that implements the ISO 7816 physical interface between thetransaction-card CPU and the memory 324 and/or 326; an application-layerprocess that implements the API and UI capabilities; the Web server 306;antenna-control functions 320; power management; and/or others. In someimplementations, the real-time OS 316 may manage the physical interfacebetween the transaction-card CPU and the secure memory 324 that includesmemory segmentation to allow certain memory areas to be restrictedaccess and/or data buffers/pipes. In some implementations, the securitymodule can include a security module OS provided by the security moduleVendor and may be compliant with Visa and MasterCard specifications. Thesecurity module OS may structure the data in the security module to becompliant with Paypass and/or payWave specifications or any otheravailable contactless retail payment industry specifications. Inaddition, the security module may store host device signatures and allowmodes of the antenna 322 in the secure element 324. In someimplementations, the real-time OS 316 may include a microcontroller OSconfigured to personalizing the secure element 324 such as by, forexample, converting raw FV data (account number, expiry date, CardVerification Number (CVN), other application specific details) intosecure encrypted information. In addition, the microcontroller OS maypresent the card 112 as a MicroSD mass storage to the host device. Themicrocontroller OS may partition the memory into a user section and aprotected device application section. In this example, the deviceapplication section may be used to store provider specific applicationsthat either operate from this segment of the memory or are installed onthe host device from this segment of the memory.

The security module chip may provide tamper-resistant hardware securityfunctions for encryption, authentication, management of user credentialsusing multiple security domains, on-board processing capabilities forpersonalization, access and storage, and/or others. In someimplementations, the security module chip can include the contactlesschipset 318.

The contactless chipset 318 may provides the hardware protocolimplementation and/or drivers for RF communication. For example, thecontactless chipset 318 may include on-board RF circuitry to interfacewith an external world connection using a wireless/contactlessconnection. The wireless connection may be, for example, client to node(terminal/reader/base station), node to client (passive tag), or peer topeer (another transaction card 112).

The antenna control function 320 may controls the availability of the RFantenna. For example, the antenna control function 320 mayactivate/deactivate the antenna 322 in response to, for example,successful authentication, completion of a routine established by the OS316, and/or other event. The antenna 322 may be a short range wirelessantenna connected to an NFC inlay via a software switch such as a NANDGate or other element.

FIG. 4 is a block diagram illustrating an example intelligent card 400in accordance with some implementations of the present disclosure. Forexample, the transaction card of FIG. 1 may be implemented in accordancewith the illustrated intelligent card 400. In general, the intelligentcard 400 may independently access services and/or transactions. Theintelligent card 400 is for illustration purposes only and may includesome, all, or different elements without departing from the scope of thedisclosure.

As illustrated, the intelligent card 400 includes an antenna 402, aswitch plus tuning circuit 404, a security module and contactlesschipset 406, a CPU 408 and memory 410. The antenna 402 wirelesslytransmits and receives signals such as NFC signals. In someimplementations, the switch plus tuning circuit 404 may dynamicallyadjust the impedance of the antenna 402 to tune the transmit and/orreceive frequency. In addition, the switch plus tuning circuit 404 mayselectively switch the antenna 402 on and off in response to at least acommand from the CPU 408. In some implementations, the antenna 402 canbe a short range wireless antenna connected to an NFC inlay via asoftware switch such as an NAND Gate or other element to allow for codefrom the CPU 408 to turn the antenna 402 on and off. In someimplementations, the card 400 may include an NFC inlay (not illustrated)that can be a passive implementation of NFC short range wirelesstechnology deriving power from the reader terminal in order to transmitdata back or a stronger implementation using an eNFC chipset to poweractive reader mode and self-train mode. In addition, the card 400 mayinclude an external needle point reset (not illustrated) that promptsthe CPU 408 to depersonalize the memory or secure element.

The CPU 408 may transmit the switching command in response to an eventsuch as a user request, completion of a transaction, and/or others. Whenswitched on, the security chip and contactless chipset 406 is connectedto the antenna 402 and executes one or more of the following: formatsignals for wireless communication in accordance with one or moreformats; decrypt received messages and encrypt transmitted messages;authenticate user credentials locally stored in the memory 410; and/orother processes. The memory 410 may include a secure and non-securedsection. In this implementation, the secure memory 410 may store one ormore user credentials that are not accessible by the user. In addition,the memory 410 may store offline Web pages, applications, transactionhistory, and/or other data. In some implementations, the memory 410 mayinclude Flash memory from 64 MB to 32 GB. In addition, the memory 410may be partitioned into user memory and device application memory. Thechipset 406 may include a security module that is, for example Visaand/or MasterCard certified for storing financial vehicle data and/or inaccordance with global standards. In addition to a user's financialvehicle, the secure element may store signatures of allowed host devicesand/or antenna modes.

In some implementations, the CPU 408 may switch the antenna 402 betweenactive and inactivate mode based, at least in part, on a personalizationparameter defined by, for example, a user, distributor (e.g., financialinstitution, service provider), and/or others. For example, the CPU 408may activate the antenna 402 when the intelligent card 400 is physicallyconnected to a host device and when a handshake with the host device issuccessfully executed. In some implementations, the CPU 408 mayautomatically deactivate the antenna 402 when the intelligent card 400is removed from the host device. In some implementations, the antenna402 is always active such that the intelligent card 400 may be used as astand-alone access device (e.g., device on a keychain). In regards tothe handshaking process, the CPU 408 may execute one or moreauthentication processes prior to activating the intelligent card 400and/or antenna 402 as illustrated in FIG. 7. For example, the CPU 408may execute a physical authentication, a device authentication, and/or auser authentication. For example, the CPU 408 may activate the antenna402 in response to at least detecting a connection to the physicalinterface with the host device (e.g., SD interface) and successfulinstallation of the device driver for mass memory access (e.g., SDdevice driver) on the host device. In some implementations, deviceauthentication may include physical authentication in addition to asignature comparison of a device signature stored in memory (e.g.,security module (SE)) that was created during first-use (provisioning)to a run-time signature calculated using, for example, a uniqueparameter of the host device. In the event no host device signatureexists in the memory, the CPU 408 may bind with the first compatiblehost device the card 400 is inserted into. A compatible host device maybe a device that can successfully accomplish physical authenticationsuccessfully. If a host-device signature is present in the memory, theCPU 408 compares the stored signature with the real-time signature ofthe current host device. If the signatures match, the CPU 408 mayproceed to complete the bootstrap operation. If the signatures do notmatch, host device is rejected, bootstrap is aborted and the card 400 isreturned to the mode it was before being inserted into the device.

User authentication may include verification of physical connection witha user using a PIN entered by the user, a x.509 type certificate that isunique to the user and stored on the host device, and/or otherprocesses. Device and user authentication may verify a physicalconnection with device through comparison of a device signature and userauthentication through verification of user PIN or certificate. In someimplementations, the user can select a PIN or certificate atprovisioning time. If this case, the CPU 408 may instantiate a softwareplug-in on the host device. For example, a software plug-in may requestthe user for his PIN in real time, read a user certificate installed onthe device (e.g., x.509), and/or others. The operation of the softwareplug-in may be customized by the provider. Regardless, the returned userdata may be compared with user data stored in the memory. In case of asuccessful match, the antenna 402 may be activated. In case of anunsuccessful match of a certificate, then card 400 is deactivated. Incase of unsuccessful PIN match, the user may be requested to repeat PINattempts until a successful match or the number of attempts exceeds athreshold. The disk provider may customize the attempt threshold.

In regards to network authentication, the host device may be a cellphonesuch that the card 400 may request network authentication prior toactivation. For example, the card 400 may be distributed by a WirelessNetwork Operator (WNO) that requires a network authentication. In thisexample, a flag in memory may be set to ON indicating that networkauthentication is required. If the flag is set to ON, a unique identityabout the allowed network is locally stored in memory such a MobileNetwork Code for GSM networks, a NID for CDMA networks, a SSID forbroadband networks, and/or identifiers. If this flag is ON, the CPU 408in response to at least insertion may request a special software plug-into be downloaded to the host device and instantiated. This softwareplug-in may query the host device to respond with network details. Insome cases, the type of unique network identity employed and the methodto deduce it from the host device may be variable and dependent on thenetwork provider and capability of the host device. If thelocally-stored ID matches the request ID, the CPU 408 activated theantenna 402 to enable access or otherwise services are denied.

FIG. 5 illustrates an example transaction system 500 for wirelesslycommunicating transaction information using one of a plurality ofinterfaces. For example, the system 500 may interface the transactioncard 112 using a wired or wireless interface. In regards to wiredinterfaces, the system 500 includes an adaptor 504 and a reader 506. Theadaptor 504 can include any software, hardware, and/or firmwareconfigured to translated between a format compatible with the card 112and a format compatible with the client 104 c. For example, the adaptor504 may translate between microSD protocol and a USB protocol. Thereader 506 can include any software, hardware, and/or firmwareconfigured to directly interface with the card 112 h. For example, thereader 506 may be a microSD reader such that the client 104 d interfaceswith the card 112 h using a microSD protocol. In regards to wirelessinterfaces, the system 500 may include a cellular interface 502 and ashort-range wireless interface 508. In regards to the cellular interface502, the financial institutions 106 may wirelessly communicate with thetransaction card 112 e using the cellular radio technology of the mobiledevice 110 e. For example, the cellular interface 502 may be a CDMAinterface, a GSM interface, a UMTS interface, and/or other cellularinterfaces. In regards to the short-range wireless interface 508, thefinancial institutions 106 may wirelessly communicate with thetransaction card 112 f using, for example, WiFi technology. Theshort-range wireless interface 508 may be an 802.11 interface, aBluetooth interface, and/or other wireless interface. In theseimplementations, the client 104 e may include a transceiver used forwireless communication with the transaction card 112 f.

FIG. 6 is a schematic diagram 600 of personalization of a intelligentcard (e.g., the transaction card 112, the service card 210). Inparticular, the intelligent card may be personalized prior to beingissued to a user, i.e., pre-issuance, or after being issued to a user,i.e., post-issuance. In regards to pre-issuance, intelligent cards maybe personalized in mass batches at, for example, a factory. In thisexample, each intelligent card may be loaded with user credentials,security framework, applications, offline Web pages, and/or other data.In some implementations, a intelligent card may be personalizedindividually at, for example, a bank branch. In this case, a intelligentcard may be individually loaded with data associated with a user after,for example, purchasing the disk. As for post issuance, the intelligentcard may be personalized wirelessly. For example, the transaction card112 may be personalized through a cellular connection established usingthe mobile device 110. In some implementations, an intelligent card maybe personalized by synchronizing with a computer such as client 104. Thetransaction card 112 may receive from an enterprise at least associatedwith the financial institution 106 that personalization data prior toactivation including user credentials, payment application and at leastone of operational flags, rule table or user interface. Thepersonalization data present in the card may be updated after activationusing at least one of the following methods: wireless or over the airmessages containing special and secure update instructions; internet orclient application running on a PC connected to the transaction card 112via the host device or a card reader; internet application wirelesslyconnecting to the transaction card 112 via the host mobile device oruser interface application of the transaction card 112 itself, and/orother methods.

In some implementations, provisioning of the intelligent card can bebased, at least in part, on the distribution entity (e.g., financialinstitution, wireless operator, user). For example, the intelligent cardmay be distributed by a financial institution such as a bank. In thebank implementation, the intelligent card can be pre-provisioned withuser accounts. In this case, the intelligent card may be activated inresponse to at least initial insertion into a host device. The antennamode may be set to physical authentication only by default. In someexamples, the user may self-select a PIN authentication to preventunauthorized use or through a PC cradle and plug-in management softwareif the host device does not have a screen and keyboard. In thewireless-operator implementation, the intelligent card may requiredevice authentication before activation. In some examples, the user mayprovision financial data (e.g., credit or debit) using one of severalmethods. In addition, the user may add user authentication. In theuser-provided implementation, the user may acquire the intelligent cardfrom, for example, a retail store or other channels like OEM host devicemanufacturers. In this case, the user may activate the card in aplurality of different devices with provider selected provisioning.

In regards to activating for financial transactions, the intelligentcard may be configured in memory mode when user acquires the disk from,for example a bank, a wireless operator, a third-party provider, and/orothers. Activation of the card may include the following two levels: 1)physically, specifying antenna availability under a specific set ofcircumstances desired by the provider; and b) logically, at thefinancial institution signifying activation of the financial vehiclecarried on the card. In some implementations, activation may be based,at least in part on device distributor, antenna availability selection,and/or type of host device as illustrated in Table 1 below.

The user mayactivate an intelligent card using the same, some, or differentprocesses without departing from the scope of this disclosure.

FIG. 7 is a flow chart illustrating an example method 700 forautomatically bootstrapping an intelligent card in response to at leastinsertion into a host device. In general, an intelligent card mayexecute one or more authentication procedures prior to activation. Manyof the steps in this flowchart may take place simultaneously and/or indifferent orders as shown. System 100 or system 200 may use methods withadditional steps, fewer steps, and/or different steps, so long as themethods remain appropriate.

Method 700 begins at step 702 where insertion into a host device isdetected. For example, the transaction card 112 may detect insertioninto the mobile device 110. If authentication is not required for anyaspect of the intelligent card at decisional step 704, then executionends. If authentication is required for at least one aspect, thenexecution proceeds to decisional step 706. If communication with thehost device includes one or more errors, then, at step 708, a failure isindicated to the user. In the example, the transaction card 112 maypresent an indication of a communication error to the user using the GUI111. If a communication error is not detected at decisional step 706,then execution proceeds to decisional step 710. In some implementations,the intelligent card uploads an SD driver to the host device. If theintelligent card only requires physical authentication, then executionproceeds to decisional step 712. If the network authentication flag isnot set to on, then, at step 714, the antenna is turned on and theintelligent card is updated with host-device signature. As for theexample, the transaction card 112 may activate the antenna for wirelesstransactions and update local memory with the host-device signature. Ifthe network authentication flag is turned on at decisional step 712,then, at step 716, the intelligent card transmits a request for thenetwork ID to the host device. Next, at step 718, the intelligent cardretrieves a locally-stored network ID. If the stored network ID and therequest network ID match at decisional step 720, then the disk isactivated at step 714. If the two network ID's do not match, then theantenna is deactivated at step 722.

Returning to decisional step 710, if the authentication is not onlyphysical authentication, then execution proceeds to decisional step 724.If the authentication process includes device authentication, then, atstep 726, the intelligent card transmits a request for a network ID tothe host device. At step 728, the intelligent card retrieves a locallystored device signatures. If the intelligent card does not include atleast one device signature, then execution proceeds to decisional step734. If the intelligent card includes one or more device signatures,then execution proceeds to decisional step 732. If one of the devicesignatures matches the request network ID, then execution proceeds todecisional step 734. If the signatures and the request network ID do notmatch, then execution proceeds to step 722 for deactivation. If userauthentication is not included in the authentication process, thenexecution proceeds to decisional step 712 for physical authentication.If user authentication is included at decisional step 734, thenexecution proceeds to step 738.

Returning to decisional step 724, if the authentication process does notinclude device authentication, then execution proceeds to decisionalstep 736. If user authentication is not included in the process, then,at step 722, the intelligent card is turned off. If user authenticationis included, then, at step 738, the intelligent card request a PINnumber from the user using the host device. While the userauthentication is described with respect to entering a PIN through themobile host device, the user may be authenticated using otherinformation such as biometric information (e.g., fingerprint). Againreturning to the example, the transaction card 112 may present a requestfor the user to enter a PIN through the GUI 111. At step 740, theintelligent card retrieves a locally-stored PIN. If the request PIN andstored PIN match at decisional step 742, then execution proceeds todecisional step 712 for physical authentication. If the request PIN andthe stored PIN do not match at decisional step 742, then executionproceeds to decisional step 744. If the number of attempts have notexceeded a specified threshold, then execution returns to step 738. Ifthe number of attempts has exceed to the threshold, then the antenna isdeactivated at step 722. In the example, if the event that thetransaction card 112 fails to authorize the device, network and/or user,the transaction card 112 may wirelessly transmit an indication to theassociated financial institution using the cellular radio technology ofthe mobile host device 110. In this case, the illustrated method 700 maybe implemented as a fraud control process to substantially preventunauthorized use of the transaction card 112.

FIG. 8 is an example call flow 800 in accordance with someimplementations of the present disclosure. As illustrated, the flow 800includes a network 802, a host device 804, an intelligent card 806, anda terminal 808. The host device 804 is configured to communicate withthe network 802 and includes a slot for insertion of the intelligentcard 806. The intelligent card 806 is configured to transmit commands toand receive data from a user interface application 810 executed by thehost device 810 and execute transactions independent of the host device810. The card 806 includes a CPU 812 for executing transactions and awireless chipset 814 for communicating with the terminal 808. The CPU812 executes a host controller/API interface 816 configured to transmitscommands in a form compatible with the host device 804 and convert datafrom the host device 804 to a form compatible with the CPU 812.

As illustrated, the flow 800 may include multiple sessions 820 betweenthe host device 804 and the card 806 and between the card 806 and theterminal 808. The session 820 a illustrates a session managed by thecard 806 using the network capabilities of the host device 810. In thisexample, the card 806 transmits data for transmission through a cellularnetwork connected to the host device 804, and after receiving thecellular data, the host device 804 transmits the data to the network802. In response to receiving data from the network 802, the host device804 may automatically transmit the received data to the card 806. Insome implementations, the card 806 may transmit a request for a devicesignature to the host device 804 as illustrated in session 820 b. Forexample, the card 806 may request the device signature during abootstrapping process. The session 820 c illustrates that a user maysubmit commands to the card 806 through the interface of the host device804. For example, the user may request that the disk display the user'stransaction history through the interface of the host device 804.

In some implementations, the card 806 may receive a command to activateor deactivate the antenna through the host device 804 as illustrated insession 820 d. For example, a financial institution may identifyirregular transactions and transmit a command through the network 802 todeactivate the card 806. The card 806 may authorize a user by requestinga PIN using the host device 804. As illustrated in session 820 e, theuser may submit a PIN to the card 806 using the interface of the hostdevice 804, and in response to an evaluation of the submitted PIN, thecard 806 may present through the host device 804 an indication that theuser verification is successful or has failed. In some implementations,a user and/or financial institution may request a transaction history ofthe card 806 as illustrated in session 820 f. For example, a financialinstitution may transmit a request for the transaction history throughthe network 802 connected to the host device 804, and in response to atlast in the request, the card 806 may transmit the transaction historyto the financial institution using the network 802 connected to the hostdevice 804. In some implementations, the user may present offline Webpages stored in the card 806 as illustrated in session 820. For example,the card 806 may receive a request to present an offline Web page fromthe user using the host device 804 and present the offline page usingthe URL in the request. In some implementations, data stored in thememory of the card 806 may be presented through, for example, the hostdevice 804 as illustrated in session 820 h. For example, the user mayrequest specific information associated with a transaction on a certaindata and the card 806 may retrieve the data and present the data to theuser using the host device 804. In addition, the user may write data tothe memory in the card 806 as illustrated in session 820 i. For example,the user may update transaction data with an annotation, and in responseto at least the request, the card 806 may indicate whether the updatewas a success or failure.

In regards to session between the card 806 and the terminal, the flow800 illustrates the personalization session 820 k and the transactionsession 820 l. In regards to personalization, a financial institutionmay personalize a card 806 with user credentials, user applications, Webpages, and/or other information as illustrated in session 820 k. Forexample, the terminal 808 may transmit a provisioning request to thecard 806 including associated data. The protocol translation 818 maytranslate the personalization request to a form compatible with the card806. In response to at least the request, the CPU 812 transmit anindication whether the personalization was a success or not using theprotocol translation 818. Prior to the terminal executing a transaction,the terminal 808 may submit a transaction challenge to the card 806 asillustrated in session 820 l. In this case, the card 806 may identify adevice signature of the host device 804, present associated data to theuser through the host device 804, and transmit the signature to theterminal 808 using the protocol translation 818.

FIG. 9 is a flow chart illustrating an example method 900 for activatinga wireless transaction system including an intelligent card. In general,an intelligent card may execute one or more activation processes inresponse to, for example, a selection from a user. Many of the steps inthis flowchart may take place simultaneously and/or in different ordersas shown. System 100 or system 200 may use methods with additionalsteps, fewer steps, and/or different steps, so long as the methodsremain appropriate.

Method 900 begins at step 902 where a request to activate a transactioncard is received. For example, the user may select a graphical elementdisplayed through the GUI 111 of a mobile host device 110 in FIG. 1. Ifan account activation is included at decisional step 904, then at step906, a request to activate the associated financial account iswirelessly transmitted to financial institution using cellular radiotechnology of the host device. For example, the transaction card 112 dof FIG. 2 may wireless transmit an activation request to the financialinstitution 106 using the cellular radio technology of the mobile hostdevice 110 d. If an account activation is not included, then executionproceeds to decisional step 908. If card activation is not included,then execution ends. If card activation is included, then executionproceeds to decisional step 910. If an activation code is not included,then at step 912, one or more preprogrammed questions are presented tothe user using the GUI of the host device. Returning to the initialexample, the transaction card 112 may identify locally stored questionsand present the questions to the user using the GUI 111 of the mobilehost device 110. At step 914, locally-stored answers to the programmedquestions are identified. Returning to decisional step 910, if anactivation code is included, then execution proceeds to decisional step916. If the activation code is manually entered by the user, then atstep 918, a request for the activation code is presented to the userthrough the GUI of the mobile host device. In the initial example, thetransaction card 112 may present a request for an activation code suchas a string of characters to the user through the GUI 111 of the mobilehost device 110. If the activation code is not manually entered by theuser, then at step 920, the transaction card wirelessly transmits arequest for the activation code using the cellular radio technology ofthe host device. In the cellular example, the transaction card 112 maytransmit a request to the financial institution using the cellular corenetwork 202. In either case, the locally-stored activation code isidentified at step 922. If the locally stored information matches theprovided information at decisional step 924, then at step 926, thetransaction card is activated. For example, the transaction card 112 mayactivate in response to at least a user entering a matching activationcode through the GUI 111. If the provided information does not match thelocally stored information, then execution ends.

FIGS. 10A and 10B illustrate example cards 1000 and 1020, respectively,for housing the transaction card 112 of FIG. 1. For example, thetransaction cards 112 may be inserted into the cards 1000 and 1020during the personalization process and/or distribution processes. Byexecuting personalization while inserted, the transaction cards 112 maybe personalized using the same systems used to personalize smart cardswith substantially no alterations. In other words, the cards 1000 and1020 may have substantially similar dimensions as smart cards such thatpersonalization systems may similarly process the cards 1000 and/or the1020. In FIG. 10A, the card 1000 includes a slot 1002 formed to hold thetransaction card 112. For example, the slot 1002 may retain thetransaction card using a frictional fit such as internal serrations.When retained in the slot 1002, the transaction card 112 may besubstantially flush with the front and back surfaces of the card 1000.In FIG. 10B, the card 1020 includes a pocket 1022 for retaining thetransaction card 112 at least adjacent a surface of the card 1020. Insome implementations, the cards 1000 and 1020 may include magneticstrips to execute contact transactions.

A number of embodiments of the invention have been described.Nevertheless, it will be understood that various modifications may bemade without departing from the spirit and scope of the invention.Accordingly, other embodiments are within the scope of the followingclaims.
